Abstract
A novel micro-displacement stage of scanning tunneling microscopy(STM) based on the principle of inchworm motion is designed.it is successful in observing atom space image.By using the finite element analysis software
research is done on the static and dynamic character of the micro-displacement stage.The experiment results show that the motion of the micro-displacement stage is stability
loading capacity is 16.7N and the mini-real step is 8.8nm
